Title:
ANTENNA MODULE, COMMUNICATION MODULE, AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/100412
Kind Code:
A1
Abstract:
This antenna module (100) includes: a dielectric substrate (130); an emission electrode (121) and a ground electrode (GND) which are disposed on the dielectric substrate (130); and a current breaker element (150) which is electrically connected to the ground electrode (GND). The ground electrode (GND) is disposed on a different layer from a layer of the emission electrode (121) in the dielectric substrate (130). The current breaker element (150) is configured to break a current flowing to the ground electrode (GND). The current breaker element (150) includes a planar electrode (151) which is parallel to the ground electrode (GND) and which has a first end part electrically connected to the ground electrode (GND) and a second end part that is in an open state. When the wavelength of a high frequency signal emitted from the emission electrode (121) is λ, the length of the first end part to the second end part of the current breaker element (150) is about λ/4.
